1. A ground engaging vehicle, comprising:
- a frame;
an engine supported by said frame, said engine operable at a rotational speed, said engine including a throttle;
a controller in communication with said engine;
an accelerator;
a position sensor associated with said accelerator, said position sensor generating a first signal corresponding to a position of said accelerator; and
an interpreter receiving said first signal from said position sensor, said interpreter generating a second signal dependent on said first signal from said position sensor, said interpreter detecting a change in said first signal from said position sensor and communicating said second signal to said controller, said second signal being said first signal modified to not exceed a predetermined rate of change of said engine speed.

Abstract
A ground engaging vehicle including a frame, an engine, a controller, an accelerator, a position sensor and an interpreter. The engine is supported by the frame and the engine includes a throttle. The controller is in communication with the engine. The position sensor is associated with the accelerator. The position sensor generates a first signal corresponding to a position of the accelerator. The interpreter receives the first signal from the position sensor and generates a second signal dependent upon the first signal. The interpreter communicates the second signal to the controller.

11. An engine control system for a ground engaging vehicle, comprising:
-
an engine including a throttle, said engine operable at a rotational speed, said engine capable of changing speed at a predetermined rate; a controller in communication with said engine; an accelerator; a position sensor associated with said accelerator, said position sensor generating a first signal corresponding to a position of said accelerator; and an interpreter receiving said first signal from said position sensor, said interpreter decreasing said first signal from said position sensor to a second signal based on said predetermined rate of engine speed, said interpreter communicating said second signal to said controller. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18, 19, 20)

22. A ground engaging vehicle, comprising:
-
a frame; an engine supported by said frame, said engine capable of changing speed at a predetermined rate; an accelerator that receives an input to change the engine speed at a desired rate; an interpreter that performs the steps of; receiving a desired throttle input signal based on the input to the accelerator; and limiting the desired throttle input signal to an actual throttle input signal when the desired rate of engine speed from the accelerator exceeds the predetermined rate of engine speed from the engine; and a throttle that controls the engine speed based on the actual throttle input signal. - View Dependent Claims (23)
